(Round your answer to two decimal places: ex: 123.45)You are taking two courses this semester, biology and chemistry. You have quizzes coming up in both classes. The table below shows your grade on each quiz for different numbers of hours studying for each quiz. For instance, the second row implies that one hour of studying for Chemistry will generate an expected grade of 73 on Chemistry, whereas one hour of studying for Biology will generate an expected grade of 75 on Biology. Hours of Study Chemistry Biology 0 65 68 1 73 75 2 79 80 3 83 83 Your goal is to maximize your average grade on the two quizzes. Use the idea of optimization in differences to decide how much time you would spend studying for each quiz if you had a total of 1, 2, or 3 hours to prepare for each exam. If you had 1 hour, you should study..... If you had 2 hours, then you should study.... hour(s) for chemistry and..... hour(s) for biology. If you had 3 hours, then you should study ..... hour(s) for chemistry and..... hour(s) for biology.…Studies have concluded that a college degree is a very good investment.

- Find the expected value assuming the risk factor is 30 % and the interest rate is 15%, if you will receive $20,000 one year from today. Find the expected value assuming the risk factor is 30 % and the interest rate is 15%, if you will receive $20,000 two years from today.Suppose your utility function for money is a square-root function of its value in US dollars. So, for instance, $400 is worth 20 utils for you, $961 is worth 31 utils for you, and $62.5K is worth 250 utils for you. Now, let’s say your annual salary is $90K, although there is a small risk (p = 0.05) that something catastrophic will happen and reduce your income for the year to $14.4K. An insurance company comes along and offers to insure you against the loss of your salary. The cost of the insurance is $4,736. If you buy the policy and catastrophe strikes, the insurance company will pay out the $75,600 that you would otherwise have lost. From the standpoint of maximizing expected utility, would buying this insurance be a good deal for you? What would be the insurance company’s expected monetary value of selling you the policy?Burger Prince Restaurant is considering the purchase of a $100,000 fire insurance policy. The fire statistics indicate that in a given year the probability of property damage in a fire is as follows: Fire Damage $100,000 $75,000 $50,000 $25,000 $10,000 $0 Probability .006 .002 .004 .003 .005 .980 If Burger Prince was risk neutral, how much would they be willing to pay for fire insurance? If Burger Prince has the utility values given below, approximately how much would they be willing to pay for fire insurance? Loss $100,000 $75,000 $50,000 $25,000 $10,000 $5,000 $0 Utility 0 30 60 85 95 99 100

The first project involves expanding the market for bologna; the second involves expanding the market for caviar. There is a 10 percent chance of a recession and a 90 percent chance of an economic boom. During a boom, the bologna project will lose $10,000, whereas the caviar project will earn $20,000. During a recession, the bologna project will earn $12,000 and the caviar project will lose $8,000. If the alternative is earning $3,000 on a safe asset (say, a Treasury bill), what should the manager do? Why?If a risk‐neutral individual owns a home worth $200,000 and there is a three percent chance the home will be destroyed by fire in the next year, then we know that:a) He is willing to pay much more than $6,000 for full cover.b) He is willing to pay much less than $6,000 for full cover.c) He is willing to pay at most $6,000 for full cover.d) None of the above are correct.e) All of the above are correct.
- A risk-averse manager is considering a project that will cost £100. There is a 10 percent chance the project will generate revenues of £100, an 80 percent chance it will yield revenues of £50, and a 10 percent chance it will yield revenues of £500. Should the manager adopt the project? Explain. What will a risk-neutral and risk-loving manager do in the same situation?Gary likes to gamble. Donna offers to bet him $31 on the outcome of a boat race. If Gary’s boat wins, Donna would give him $31. If Gary’s boat does not win, Gary would give her $31. Gary’s utility function is p1x^21+p2x^22, where p1 and p2 are the probabilities of events 1 and 2 and where x1 and x2 are his wealth if events 1 and 2 occur respectively. Gary’s total wealth is currently only $80 and he believes that the probability that he will win the race is 0.3. Which of the following is correct? (please submit the number corresponding to the correct answer). Taking the bet would reduce his expected utility. Taking the bet would leave his expected utility unchanged. Taking the bet would increase his expected utility. There is not enough information to determine whether taking the bet would increase or decrease his expected utility. The information given in the problem is self-contradictory.There are two risky assets, namely Asset 1 and Asset 2, in the economy and only two investors, namely Alice and Bob, who can borrow or lend at the risk-free rate of 2%. The risk-free asset, though, is in a net supply of zero. Alice's initial wealth is $70,000, and Bob's initial wealth is $50,000. Alice has invested $80,000 in Asset 1 and $20,000 in Asset 2. Assume that both Alice and Bob are mean-variance efficient investors, which of the following statements is wrong? Bob has invested $16,000 in Asset 2 The market capitalization of Asset 2 is $24,000 Bob has lent Alice $30,000 The market capitalization of Asset 1 is $80,000
